So like Schrödinger's cat they could simultaneously be borth? So what part of the law tips them one way or the other?
Of course they could be be both, but not like Schrödinger's Cat, the cat will be one or the other when someone checks. But even one's status is collapsed, one can be both "native born" and "natural born". The sets "citizen" or "native born citizen", and "natural born citizen" can overlap. It's only "natural born citizen" and "naturalized citizen" that are non-overlapping.
A Venn diagram would be clearer, but I have no way of creating and posting one.
Denial of the The Excluded Middle, often leads to false conclusions.
